Abstract

"MONTAGEM DE FERRAMENTA DE FURO DE SONDAGEM, SISTEMA DE MANCAL, E, MéTODO PARA PROJETAR UMA MONTAGEM DE FERRAMENTA DE FURO DE SONDAGEM". Montagem de ferramenta de furo de sondagem incluindo um alojamento e um mandril alcançando ao longo de uma direção axial no alojamento e um sistema de mancal para transferir uma carga axial entre o alojamento e o mandril e permitir rotação do alojamento relativo e sobre o mandril, em que o sistema de mancal inclui pelo menos dois estágios de mancal, cada um arranjado para transferir parte da carga axial, por meio de que cada estágio de mancal inclui meio de mancal e meio de atenuação para distribuir a carga substancialmente proporcionalmente através dos estágios de mancal respectivos."DRILL HOLE TOOL ASSEMBLY, BEARING SYSTEM, AND METHOD FOR DESIGNING A DRILL HOLE TOOL ASSEMBLY". Borehole tool assembly including a housing and a mandrel reaching along an axial direction in the housing and a bearing system for transferring an axial load between the housing and the mandrel and permitting rotation of the relative housing and about the mandrel whereas the bearing system includes at least two bearing stages, each arranged to transfer part of the axial load, whereby each bearing stage includes bearing means and attenuation means to distribute the load substantially proportionally through the bearing stages. related.
